Once in Safe Mode, open the SmitfraudFix folder again and double-click smitfraudfix.cmd
Select option #2 - Clean by typing 2 and press "Enter" to delete infected files.

You will be prompted : "Registry cleaning - Do you want to clean the registry ?"; answer "Yes" by typing Y and press "Enter" in order to remove the Desktop background and clean registry keys associated with the infection.

The tool will now check if wininet.dll is infected. You may be prompted to replace the infected file (if found); answer "Yes" by typing Y and press "Enter".

The tool may need to restart your computer to finish the cleaning process. A text file will appear onscreen, with results from the cleaning process; please copy/paste the content of that report into your next reply.

After SmitfraudFix finishes (and after a reboot if required), do a antivirus scan and tell me if its clean.
